This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 849620206. Listed at 4 retailers as of November 4, 2026, with prices from $6,688 to $13,092, a $6,404 spread on the same certified stone. MOH London lists it at $13,092. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
